Played around in single player.
The movement feels good, it was cool to go around and talk to NPCs and managed to propel myself really high using two rocket launchers. Tried to play online but couldn't find anyone on the server sadly. I know you are deciding between PVP and exploration. I think both can fit nicely if you work on them, so don't worry too much about which one you chose.
I tried to record myself playing, but OBS didn't catch my "start recording" hotkeys so I don't have a video file, sorry.
